54F/74F191  
Up/Down Binary Counter with Preset and Ripple Clock  
General Description  
Features  
The ’F191 is a reversible modulo-16 binary counter featur-  
ing synchronous counting and asynchronous presetting.  
The preset feature allows the ’F191 to be used in program-  
mable dividers. The Count Enable input, the Terminal Count  
output and Ripple Clock output make possible a variety of  
methods of implementing multistage counters. In the count-  
ing modes, state changes are initiated by the rising edge of  
the clock.
